About
A universal PCR master mix for allele-specific PCR assays. Precision fluorescent signal generation with consistently high performance at any reaction volume.
PACE Genotyping Master Mix uses a novel, universal, fluorescent reporting cassette to produce machine-readable fluorescent signals corresponding to genotypes. PACE compatible genotyping assays are comprised of two competitive allele specific forward primers (which differ in their terminal 3’ bases and unique 5’ tail sequences) and a common, reverse primer. PACE Genotyping Master Mix is supplied at 2x concentration and with ROX normalising dye at a range of levels to ensure compatibility with your qPCR instrument or reader.
Genotyping assay designs are available from 3CR Bioscience through our free PACE assay-design service; once designed, users can purchase assay primers independently or through 3CR Bioscience using our partial or full-assay validation service. PACE Genotyping Master Mix is also compatible with KASP™ and Amplifluor® marker assays.

Cod Uracil-DNA Glycosylase (Cod UNG) from Atlantic Cod is the only commercially available UNG enzyme that is completely and irreversibly inactivated by moderate heat treatment. The enzyme is produced in a recombinant E. coli (ung-) strain that contains a modified Cod UNG gene.
Key Features:
Heat-labile – Completely and irreversibly inactivated at 55°C
Contamination control – ideal in applications below
Use of Cod UNG makes contamination control possible in RT-PCR
Does not degrade PCR product post-PCR. This makes downstream use of the PCR product possible
High purity enzyme, tested free of contaminating nucleases
There are several commercially available Uracil-DNA glycosylases on the market today. Most of them are of bacterial origin and work well if you have no intention to further analyze the PCR products post-PCR. However, if you want to store your PCR products for downstream analysis such as cloning and sequencing, the reactivation of UNG and subsequent degradation of your PCR products are a problem with most of the commercially available UNGs. Cod UNG from ArcticZymes is completely and irreversibly inactivated by heat thus ensuring that sample integrity is maintained long-term regardless of storage conditions.
This is illustrated in figure 1, below

Properties
Recommended Protocols
1. Contamination control in PCR, qPCR and one-step RT-qPCR
Cod UNG works in all commercially available master mixes.
Be sure that you have used dUTP containing dNTP mixes in your previous PCR experiments.
Add 0.2 U Cod UNG directly to your 20 µl PCR reaction.
pre-incubate for 5 min at room temperature.
For RT-qPCR, reverse transcribe your RNA at 50-55°C.
Run your PCR.
Store your PCR product at -20°C or 4°C degrees.
2. Contamination control in RT-LAMP
Cod UNG is ideal for contamination control in RT-LAMP. One unit of Cod UNG per 30 μl reaction is sufficient for removing even high concentrations of carry-over contamination.
Ensure that you use dNTP mixes containing dUTP in your experiments.
Check that the RT-LAMP reaction is compatible with dUTP by running side-by-side reactions containing different ratios of dUTP to dUTP (100% dUTP, 90% dUTP, 80% dUTP and 0% dUTP).
Add 1 U Cod UNG directly to your 30 µl RT-LAMP reaction.
Prepare the reaction mix on ice.
Analyze your RNA at 65°C, no preincubation is necessary.
